I could probably look this up on the TINS website, but what are the rules about using helper libraries? Gotta be published and available 2 weeks before the compo? I vote for whenever, I don't know my schedule yet.

Edgar: you don't need to provide them if they can be found on the WEB, AFAIK

Edit, now to the OP:

Source: I would prefer a system where competitors who also provide sources gets at least one more point creditedAllegro: The same as sources, if used it gives bonus, else nothing.Marketing: On that part I think we can all help, just by sharing the news as soon as we got the dates

I will probably start to do some advertising for TINS, even if not needed, just for the sake of not always being the only one French to join.

I'm polishing my engine (Allegro based). It is not a stand alone engine like Unity, I mean it is a collection of classes and objects you link with the game program; so it works as a library. There isn't problems using it, is it?
